FIG. 3 is a diagram illustrating a printed circuit board within an exemplary electronic device according to various embodiments.

The electronic device (100) may include a heat transfer system that dissipates heat generated (or emitted) from heat-generating components of the electronic device (100) to the outside. The heat transfer system of the electronic device (100) may thermally connect the heat-generating component and a structure of the electronic device to spread heat through the structure. The structure may include a surface area for dissipating heat. For example, the heat-generating component may be an integrated circuit (IC) such as a processor or a chip, and the structure may be a component (e.g., a frame, a bracket, or a case) that forms an outer shape of the electronic device or supports internal components.

A heat transfer system can spread heat generated from a heat generating component to the structure through a heat dissipation structure. The heat dissipation structure can provide a heat diffusion path from the heat generating component to the structure.

Since the electronic device (100) includes many high-performance components, the electronic device (100) may include a plurality of heat dissipation structures (330, 340) to separate heat diffusion paths between the heat-generating components.

Referring to FIG. 3, the electronic device (100) may include a printed circuit board (150) disposed within a housing (110).

The electronic device (100) may further include components (e.g., electronic components) (311, 312, 321, 351), a first shield can (310), a second shield can (320), and a heat dissipation structure (330). In order to miniaturize the electronic device (100) and implement multiple functions, many components (311, 312, 321, 351) may be placed on a printed circuit board (150). The electronic device (100) may further include a shield can (310, 320) for noise shielding between the components (311, 312, 321, 351). The components (311, 312, 321, 351), the first shield can (310), and the second shield can (320) may be placed on a printed circuit board (150). The heat dissipation structure (330) may be supported by the first shield can (310) and the second shield can (320). For example, one end of the heat dissipation structure (330) may be connected to the first shield can (310), and the other end of the heat dissipation structure (330) may be connected to the second shield can (320).

The components (311, 312, 321, 351) may emit or generate heat during operation of the electronic device (100). For example, during operation of the electronic device (100), the components (311, 312, 321, 351) may generate heat, and the generated heat may be emitted. Some of the components (311, 312, 321, 351) may be placed within the shield candles (310, 320). For example, the first component (311) and the second component (312) may be placed in a cavity within the first shield can (310). The third component (321) may be placed in a cavity within the second shield can (320). The first component (311) and the second component (312) may emit or generate more heat than the other components (351). For example, the first component (311) and the second component (312) may be an integrated circuit (IC), a chip, a heat-generating component, an application processor (AP), a communication processor (CP), or a power management integrated circuit (PMIC). The component (351) may assist the operation of the components (311, 312, 321). The component (351) may be a device disposed outside the shield candle (310, 320). For example, the component (351) may be at least one of a capacitor, an inductor, or a resistor.

For example, components (351) may be placed around the first component (311). Passive components such as resistors, capacitors, or inductors may be placed around high-performance components such as the first component (311). Components that dissipate a lot of heat, such as the first component (311) or the second component (312), may be located at the periphery of the printed circuit board (150) or the periphery of the space enclosed by the shield can (310). For example, the first component (311) or the second component (312) may be placed adjacent to a side wall of the shield can (310) within the internal space defined by the shield can (310).

The first shield can (310) can wrap some of the components arranged on the printed circuit board (150). For example, the first shield can (310) can provide a space capable of accommodating at least one component. For example, the first shield can (310) can provide a space in which the first component (311) and the second component (312) are arranged. The first shield can (310) can wrap the first component (311) and the second component (312). The second shield can (320) can wrap other components among the components arranged on the printed circuit board (150). For example, the second shield can (320) can provide a space in which the third component (321) is arranged. The second shield can (320) can wrap the third component (321).

The first shield can (310) and the second shield can (320) may include a metal material. The first shield can (310) and the second shield can (320) may be formed of a metal plate. The first shield can (310) and the second shield can (320) may be metal cases formed from a metal plate through a pressing process having an internal space. The first shield can (310) and/or the second shield can (320) may include a nickel-silver (nickel-brass) material, a copper alloy, and/or stainless steel. The first shield can (310) and the second shield can (320) formed of a metal material can prevent or reduce external noise signals or electromagnetic waves from being transmitted into the first shield can (310) and the second shield can (320), and the first shield can (310) and the second shield can (320) can prevent or reduce electromagnetic waves generated by components (311, 312, 321) inside the first shield can (310) and the second shield can (320) from being transmitted to the outside of the first shield can (310) or the outside of the second shield can (320). For example, the first shield can (310) and the second shield can (320) can block noise transmitted from external components in order to provide stable operation of the components inside the shield cans. The first shield can (310) can block electromagnetic waves resulting from the operations of other components (321, 351) from being transmitted into the first shield can (310) for the operations of the first component (311) and the second component (312) arranged in the internal space of the first shield can (310). The second shield can (320) can block electromagnetic waves resulting from the operations of other components (311, 312, 351) from being transmitted into the second shield can (320) for the operations of the third component (321) arranged in the internal space of the second shield can (320).

The electronic device (100) may further include a heat transfer material, a heat transfer structure, or a heat dissipation structure to provide a diffusion path for heat generated from the components (311, 312, 321). For example, the electronic device (100) may include a first heat dissipation structure (330) for the component (311) and/or a heat dissipation structure (340) for the second component (312). Each of the heat generated from the first component (311) and the second component (312) may be transferred along an independent path. The heat dissipation structure (330) for the first component (311) may connect the shield candle (310, 320). For example, one end of the heat dissipation structure (330) may be connected to the first shield can (310), and the other end of the heat dissipation structure (330) may be connected to the second shield can (320). The heat dissipation structure (330) may include a thermally conductive material or a heat transfer material therein. The thermally conductive material may be a liquid or gel mixed with particles having high thermal conductivity. The thermally conductive material may have viscosity. For example, the thermally conductive material may include thermal grease. The heat dissipation structure (330) may be thermally connected to the first component (311) inside the first shield can (310). The heat dissipation structure (330) may be thermally connected to the inside of the second shield can (320). The heat dissipation structure (330) can diffuse heat generated from the first component (311) into the interior of the second shield can (320).

The heat dissipation structure (340) can be thermally connected to the second component (312) within the first shield can (310). The heat dissipation structure (340) can be thermally connected to a cooling region within the electronic device (100). The cooling region can include at least one of a housing (110) of the electronic device (100), a portion of a frame structure (e.g., a frame structure (140) of FIG. 1) (e.g., a support portion (143) of FIG. 2), or an area having no or few heat-generating components. The heat dissipation structure (340) can be thermally connected to the second component (312) via a heat transfer material (e.g., thermal grease, a thermal interface material (TIM), or a nano TIM). The heat dissipation structure (340) may include one of a plate having a thermally conductive material (e.g., a graphite sheet), a metal plate, a structure including a phase change material therein (e.g., a heat pipe), or a vapor chamber. The heat dissipation structure (340) may transfer heat generated from the second component (312) to the cooling region, thereby dissipating the heat to the outside of the electronic device (100). The first component (311) and the second component (312) within the first shield can (310) may separate the heat dissipation paths. Due to the separated heat dissipation paths, the influence of heat between the first component (311) and the second component (312) may be reduced.

Since the first component (311) is positioned adjacent to the side of the first shield can (310) and there is insufficient space for application of the heat dissipation structure, it may be difficult for the first component (311) to dissipate heat through a heat pipe or metal plate, such as the heat dissipation structure (340) for the second structure (340). When a heat conductive material extending from the heat dissipation structure (330) including a heat conductive material (liquid TIM) therein comes into contact with the first component (311), the first component (311) of the electronic device (100) can spread the generated heat to the second shield can (320).

The connection structure and heat diffusion path of the heat dissipation structure (330) and the shield candle (310, 320) placed within the area P are described in more detail below with reference to FIGS. 4a to 10.

FIG. 4a is a diagram illustrating an arrangement of an exemplary shield candle and a heat dissipation structure according to various embodiments. FIG. 4b is a cross-sectional view illustrating an exemplary shield candle and a heat dissipation structure according to various embodiments.

FIG. 4a illustrates a region P of FIG. 3 in more detail, and FIG. 4b illustrates a cross-section of a heat dissipation structure (330) and a peripheral structure (e.g., a first shield can (310) and a second shield can (320)) of FIG. 4a in more detail. Referring to FIGS. 4a and 4b, the heat dissipation structure (330) may be arranged between the first shield can (310) and the second shield can (320). The first shield can (310) may provide a first space (410) (cavity) that accommodates a first component (311). For example, the first shield can (310) may surround the first component (311) and the peripheral components. The first component (311) and the peripheral components may be arranged within the first space (410). The first component (311) adjacent to the side (411) (or side wall) of the first shield can (310) may be difficult to connect to a heat dissipation structure (e.g., the heat dissipation structure (340) of FIG. 3) connected to a second component (e.g., the second component (312) of FIG. 3) due to insufficient space between the first shield can (310) and the first component (311). In order to spread the heat generated from the first component (311), the heat dissipation structure (330) may be connected to the first component (311), and the heat dissipation structure (330) may be connected to the second shield can (320). The heat dissipation structure (330) may transfer the heat generated from the first component (311) into the interior of the second shield can (320). The second shield can (320) can provide a second space ((420). For example, the second shield can (320) can surround components (e.g., the third component (321) of FIG. 3) placed inside.

The first shield can (310) may include an opening (412) for connection to a heat dissipation structure (330), and the second shield can (320) may include an opening (422) for connection to a heat dissipation structure (330).

The opening (412) of the first shield can (310) may be formed on at least one side of the first shield can (310). For example, the opening (412) may be formed on a side (411) of the first shield can (310) that faces the second shield can (320) or is close to the second shield can (320). The opening (412) may be formed on the side (411) and the upper surface (411') of the first shield can (310) that is in contact with the side (411). As one end of the heat dissipation structure (330) is inserted into the opening (412), the heat dissipation structure (330) may be supported on the side (411) of the first shield can (310). The opening (412) of the first shield can (310) may be spaced apart from the first component (311). For example, the first component (311) may overlap the first shield can (310) when one surface of the first component (311) that contacts the thermally conductive material (430) is viewed in a vertical direction. A portion of the upper surface (411') of the first shield can (310) may be placed on the first component (311).

The opening (422) of the second shield can (320) may be formed on at least one side of the second shield can (320). For example, the opening (422) may be formed on a side (421) of the second shield can (320) that faces the first shield can (310) or is close to the first shield can (310). The opening (422) may be formed on the side (421) and the upper surface (421') of the second shield can (320) that is in contact with the side (421). As the other end of the heat dissipation structure (330) is inserted into the opening (422), the heat dissipation structure (330) may be supported on the side (421) of the second shield can (320).

The heat dissipation structure (330) may further include a fastening structure for being fixed to the first shield can (310) and the second shield can (320). For example, the heat dissipation structure (330) may include a first leg set (416, 417) for being fastened to the first shield can (310). The heat dissipation structure (330) may include a second leg set (426, 427) for being fastened to the second shield can (320). The first leg set (416, 417) and the second leg set (426, 427) may limit movement of the heat dissipation structure (330) in the x-axis direction and the y-axis direction. For example, the legs (416, 417, 426, 427) of the first leg set (416, 417) and the second leg set (426, 427) may extend from the outer surface of the heat dissipation structure (330) toward the printed circuit board (150). The legs (416, 417, 426, 427) may extend in a direction perpendicular to the printed circuit board (150) and be secured to the side surface (411) of the first shield can (310) and the side surface (421) of the second shield can (320). For example, the first leg set (416, 417) may be fitted to the side surface (411) of the first shield can (310). The second set of legs (426, 427) can be fitted to the side (421) of the second shield can (320). By the legs (416, 417, 426, 427) that extend in a vertical direction to the printed circuit board (150) and are fixed to the shield can (310, 320), the heat dissipation structure (330) can be restricted from moving in a direction parallel to the printed circuit board (150).

The heat dissipation structure (330) may be formed of a metal material. The heat dissipation structure (330) may be formed of the same material as the shield candle (310, 320). For example, the heat dissipation structure (330) may include a nickel-plated material, a copper alloy, and/or stainless steel. However, the present invention is not limited thereto, and the heat dissipation structure (330) may be formed of a different metal material from the shield can.

The heat dissipation structure (330) may be formed integrally with the legs (416, 417, 426, 427). For example, the legs (416, 417, 426, 427) may be welded to the heat dissipation structure (330) at the area (w).

One of the legs of the first leg set (416, 417) can be joined to the heat dissipation structure (330), and one of the legs of the second leg set (426, 427) can be joined to the heat dissipation structure (330). For example, the leg (417) of the first leg set (416, 417) and the leg (426) of the second leg set (426, 427) can be joined to the heat dissipation structure (330). The leg (417) and the leg (426) can be in contact with the outer surface of the first shield can (310) and the outer surface of the second shield can (320), thereby limiting movement of the heat dissipation structure (330). For another example, a leg (416) of the first set of legs (416, 417) and a leg (427) of the second set of legs (426, 427) may be joined to the heat dissipation structure (330). The legs (416) and (427) may be in contact with the inner surface of the first shield can (310) and the inner surface of the second shield can (320), thereby limiting movement of the heat dissipation structure (330).

The heat dissipation structure (330) may include a heat conductive material (430) that occupies at least a portion of the internal space of the heat dissipation structure (330), extends from the heat dissipation structure (330) to contact the first component (311), and extends from the heat dissipation structure (330) to be arranged in the second space (420) of the second shield can (320). The heat dissipation structure (330) may further include an inlet (401), a first opening (402), and a second opening (403). The inlet (401) may be an opening for supplying a heat conductive material (430) (e.g., liquid TIM or thermal grease) into the interior of the heat dissipation structure (330). The inlet (401) may include a valve for reducing backflow of the heat conductive material (430) introduced into the interior of the heat dissipation structure (330). The injection port (401) may be arranged between the first opening (402) and the second opening (403). The first opening (402) and the second opening (403) may be arranged at both ends of the heat dissipation structure (330). Using the first opening (402) and the second opening (403), the amount of the thermally conductive material (430) introduced through the injection port (401) may be confirmed. When the thermally conductive material (430) is injected through the injection port (401) and moves to both ends of the heat dissipation structure, the thermally conductive material (430) injected through the first opening (402) and the second opening (403) may be identified from the outside of the heat dissipation structure (330). Based on the thermally conductive material (430) identified from the outside, the thermally conductive material (430) introduced into the shield candle (310, 320) can be confirmed.

The thermally conductive material (430) may include a first portion (431) disposed in at least a portion of the internal space of the heat dissipation structure (330), a second portion (432) extending from one end of the heat dissipation structure (330) to at least one surface of the first component (311), and a third portion (433) extending from the other end of the heat dissipation structure (330) to the second space (420) of the second shield can (320). The thermally conductive material (430) may be thermally connected to the first component (311). Heat generated from the first component (311) may spread to the second space (420) through the thermally conductive material (430).

The second portion (432) may be a portion where the thermally conductive material (430) introduced through the injection port (401) comes into contact with one surface (e.g., the upper surface) of the first component (311) through an outlet formed at one end of the heat dissipation structure (330). The third portion (433) may be a portion where the thermally conductive material (430) introduced through the injection port (401) comes into contact with the second space (420) through an outlet formed at the other end of the heat dissipation structure (330). The third portion (433) may be placed on a component that does not generate heat or generates little heat within the second space (420). The third portion (433) may be placed on a surface of a printed circuit board (150) that does not have a component within the second space (420). The third portion (433) can contact a part of the second shield can (320) to spread heat to the second shield can (320).

The tape (450) can be attached to a portion of an outer surface of the first shield can (310), a portion of an outer surface of the heat dissipation structure (330), and a portion of an outer surface of the second shield can (320). The tape (450) can extend along the outer surface of the first shield can (310), the outer surface of the second shield can (320), and the outer surface of the heat dissipation structure (330). The outer surface of the first shield can (310), the outer surface of the second shield can (320), and the outer surface of the heat dissipation structure (330), along which the tape (450) extends, can be substantially continuous surfaces. The tape (450) can be attached to the continuous surfaces to fix the heat dissipation structure to the first shield can and the second shield can. The tape (450) can restrict movement of the heat dissipation structure (330) in the z-axis direction. The tape (450) can reduce or prevent leakage of the heat conductive material (430) inside the heat dissipation structure (330). The tape (450) can be attached to the outer surface of the heat dissipation structure (330) to isolate the inside and the outside of the heat dissipation structure (330). For example, the tape (450) can wrap the injection port (401), the first opening (402), and the second opening (403).

The tape (450) may include a conductive material. The tape (450) may be grounded by the conductive material. The tape (450) that is grounded may improve the shielding performance of the first shield can (310) and the second shield can (320).

In order to strengthen the fastening force between the heat dissipation structure (330) and the first shield can (310), an adhesive may be placed between the heat dissipation structure (330) and the opening (412) of the first shield can (310). In order to strengthen the fastening force between the heat dissipation structure (330) and the second shield can (320), an adhesive may be placed between the heat dissipation structure (330) and the opening (422) of the second shield can (320).

According to the above-described embodiment, by including the injection port (401), the first opening (402), and the second opening (403), the heat dissipation structure (330) can transfer a heat transfer material to the first component (311) and the second space (420) after being fixed to the first shield can (310) and the second shield can (320). By diffusing heat generated from the component (311) to the second space (420) through the transferred heat transfer material, stable performance of the electronic device (100) can be maintained.

FIGS. 5A and 5B are perspective views illustrating exemplary heat dissipation structures according to various embodiments. Referring to FIG. 5A, the heat dissipation structure (330) may include a case (500). The case (500) may have a hollow hole. The case (500) may be a pipe with both ends open. The case (500) may provide an inflow path for a heat conductive material (e.g., a heat conductive material (430) of FIG. 4B) introduced through an inlet (401). For example, the case (500) may guide the movement of the heat conductive material.

The cross section of the case (500) may have a pipe shape. The pipe may be a square pipe, or a polygonal or circular pipe. The shape of the pipe may be determined according to the position in which it is placed within the electronic device (e.g., the electronic device (100) of FIG. 1) or the surrounding environment of the heat dissipation structure (330).

The heat dissipation structure (330) may include an injection port (401), a first opening (402), and/or a second opening (403) formed on an outer surface of the case (500). The injection port (401) may be positioned between the first opening (402) and the second opening (403). The injection port (401) may be a passage through which a nozzle for injecting a heat conductive material passes. The first opening (402) and the second opening (403) may be formed on an outer surface of the case (500) to confirm the heat conductive material inside the case (500) injected through the injection port (401). The injection port (401), the first opening (402), and the second opening (403) may face the same direction on the outer surface of the heat generating structure (330). For example, the injection port (401), the first opening (402), and the second opening (403) may be formed on one surface of the case (500). The injection port (401) may be formed on the upper surface of the case (500) of the heat dissipation structure (330), and the first opening (402) and the second opening (403) may be formed on the upper surface of the case (500) where the injection port (401) is formed. For example, when the case (500) is circular, the first opening (402) and the second opening (403) may be arranged to face a direction parallel to the direction in which the injection port (401) faces.

The heat dissipation structure (330) may further include a first discharge port (510) and a second discharge port (520). The first discharge port (510) may be formed at one end (501) of the heat dissipation structure (330). The second discharge port (520) may be formed at the other end (502) of the heat dissipation structure (330). The first discharge port (510) and the second discharge port (520) may move a heat conductive material introduced from the inlet (401) to the outside of the case (500). For example, through the first discharge port (510), a portion of the heat conductive material inside the case (500) may be moved to a first shield can (e.g., the first shield can (310) of FIG. 3). Through the second exhaust port (520), another portion of the thermally conductive material within the case (500) can be transferred to the second shield can (e.g., the second shield can (320) of FIG. 3). The first exhaust port (510) can be formed at one end (501) of the case (500) (or the heat dissipation structure (330)). The second exhaust port (520) can be formed at the other end (502) of the case (500) (or the heat dissipation structure (330)). For example, the first exhaust port (510) and the second exhaust port (520) can be open portions located at both ends (501, 502) of the hollow hole. The first exhaust port (510) can connect the interior of the case (500) and the first space (410) of the first shield can (310). The second exhaust port (520) can connect the interior of the case (500) and the second space (420) of the second shield can (320). The amount of thermally conductive material flowing into the first shield can (310) can be different from the amount of thermally conductive material flowing into the second shield can (320). For example, the amount of thermally conductive material passing through the first exhaust port (510) can be different from the amount of thermally conductive material passing through the second exhaust port (520). The areas of the first exhaust port (510) and the second exhaust port (520) can be the same. For example, the cross-sectional area of the pipe-shaped case (500) can be substantially the same at a plurality of points. Pipes having the same internal cross-sectional area can deliver the thermally conductive material at the same rate (or in the same amount). In order to make the amount of heat conductive material transferred from the first outlet (510) and the second outlet (520) different, the inlet (401) may be arranged offset from one of the ends of the heat dissipation structure (330). For example, as shown in FIG. 5A, the heat dissipation structure (330) may include an inlet (401') that is closer to the second outlet (520) than to the first outlet (510), instead of the inlet (401). The inlet (401') may be arranged closer to the other end (502) of the heat dissipation structure (330) than to one end (501) of the heat dissipation structure (330).

An amount of a thermally conductive material injected through an inlet (401) spaced apart from one end (501) of a heat dissipation structure (330) and the other end (502) of the heat dissipation structure (330) by substantially the same distance and delivered to the first shield can (310) through the first outlet (510) may be substantially the same as an amount of a thermally conductive material injected through the inlet (401') and delivered to the first shield can (310) through the first outlet (510). An amount of a thermally conductive material injected through the inlet (401') and delivered to the first shield can (310) through the first outlet (510) may be less than an amount of a thermally conductive material delivered to the second shield can (310) through the second outlet (520).

The heat dissipation structure (330) may include outlets (510', 520) of different areas, as shown in FIG. 5b. For example, a first outlet (510') arranged at one end (501) of the heat dissipation structure (330) may be narrower than a second outlet (520) arranged at the other end (502) of the heat dissipation structure (330). The area of the first outlet (510') may be smaller than the area of the second outlet (520). The amount of heat conductive material transferred to the first shield can (310) through the relatively narrow first outlet (510') may be less than the amount of heat conductive material transferred to the second shield can (320) through the second outlet (520).

The heat dissipation structure (330) can control the amount of heat conductive material transferred to the first shield can (310) and the amount of heat conductive material transferred to the second shield can (320) by making the widths of the first discharge port (510 or 510') and the second discharge port (520) different or by arranging the inlet ports (401 or 401') differently.

FIG. 6 is a cross-sectional view of an exemplary shield candle and a heat dissipation structure disposed on a component within the shield can according to various embodiments. FIG. 7 is a perspective view of an exemplary heat dissipation structure having an exhaust port facing a component according to various embodiments.

Referring to FIGS. 6 and 7, the first shield can (310) may include an opening (611). The opening (611) may be formed on a side surface (411) that contacts the heat dissipation structure (330) and an upper surface (411') that contacts the side surface (411). The opening (611) may be formed so that the heat dissipation structure (330) can be placed on the first component (311). For example, a part of the upper surface (411') of the first shield can (310) may be removed. When one surface (311a) of the first component (311) that contacts the second portion (432) of the thermally conductive material (430) is viewed in a vertical direction, the first component (311) may be spaced apart from the upper surface (411') of the first shield can (310). A part of the heat dissipation structure (330) that penetrates the opening (611) of the first shield can (310) and is placed in the first space (410) of the first shield can (310) can be placed on the first part (311).

The heat dissipation structure (330) may include a first discharge port (710) facing the first component (311) and a second discharge port (720) formed at another end (702) of the heat dissipation structure (330). The first discharge port (710) may be positioned adjacent to one end (701) of the heat dissipation structure (330). When one side of the first component (311) contacting the second portion (432) is viewed vertically, the first discharge port (710) of the heat dissipation structure (330) may overlap the first component (311). The first discharge port (710) may contact the first component (311). However, the present invention is not limited thereto, and the first discharge port (710) may be spaced apart from the first component (311).

A portion of the heat conductive material (430) introduced through the inlet (401) of the heat dissipation structure (330) may be located inside the heat dissipation structure (330). The heat conductive material (430) may include a first portion (431) located inside a portion of the heat dissipation structure (330), a second portion (432) in contact with the first component (311), and a third portion (433) disposed in the second space (420) of the second shield can (320) through a second discharge port (720) formed in another end (702) of the heat dissipation structure (330).

When the first discharge port (710) of the heat dissipation structure (330) comes into contact with the first component (311), the heat conductive material (430) inside the first shield can (310) may not be transferred to the first space (410) of the first shield can (310) through the first discharge port (710). The second portion (432) of the heat conductive material (430) may absorb only the heat generated from the first component (311), thereby rapidly diffusing the heat of the first component (311) to the second space (420) of the second shield can (320).

FIG. 8 is a drawing showing an exemplary application operation of a heat transfer material transmitted through an exemplary heat dissipation structure according to various embodiments.

Referring to FIG. 8, the injection nozzle (800) can supply a thermally conductive material (e.g., the thermally conductive material (430) of FIG. 4b or FIG. 6) into the interior of the electronic device (100). The injection nozzle (800) can be inserted into the heat dissipation structure (330) through the injection port (401). The thermally conductive material can be injected into the interior of the heat dissipation structure (330) through the injection nozzle (800) inserted into the interior of the heat dissipation structure (330). The injection port (401) can have a backflow prevention valve to reduce the injected thermally conductive material from flowing out of the heat dissipation structure (330) through the injection port (401).

The thermally conductive material transferred into the interior of the heat dissipation structure (330) can be transferred to both ends of the heat dissipation structure (330). For example, a portion of the thermally conductive material transferred into the interior of the heat dissipation structure (330) can be transferred to one end (501) of the heat dissipation structure (330), and another portion of the thermally conductive material transferred into the interior of the heat dissipation structure (330) can be transferred to the other end (502) of the heat dissipation structure (330). A portion of the thermally conductive material inside the heat dissipation structure (330) can be transferred to one end (501) of the heat dissipation structure (330) along the first path (P1). A portion of the thermally conductive material transferred to one end (501) of the heat dissipation structure (330) can be transferred to the outside of the heat dissipation structure (300) through the first discharge port (510). A portion of the heat conductive material transferred within the heat dissipation structure (330) along the first path (P1) can be identified to an operator via the first opening (402). Another portion of the heat conductive material within the heat dissipation structure (330) can be transferred to another end (502) of the heat dissipation structure (330) along the second path (P2). Another portion of the heat conductive material transferred within the heat dissipation structure (330) along the second path (P1) can be identified to an operator via the second opening (403). Another portion of the heat conductive material transferred to another end (502) of the heat dissipation structure (330) can be transferred to the exterior of the heat dissipation structure (330) via the second outlet (520).

A portion of the thermally conductive material delivered to the first discharge port (510) may be delivered to the first space (410) of the first shield can (310) along the third path (P3). A portion of the thermally conductive material delivered within the first shield can (310) may be disposed on the first component (311). Another portion of the thermally conductive material delivered to the second discharge port (520) may be delivered to the second space (420) of the second shield can (320) along the fourth path (P4). Another portion of the thermally conductive material delivered within the second shield can (320) may be applied to the inner surface of the second shield can (320) or may be applied on the printed circuit board (150) within the second shield can (320).

FIG. 9 is a diagram illustrating exemplary heat transfer paths emitted from components inside a shield can according to various embodiments.

Referring to FIG. 9, heat generated from the first component (311) may be transferred along a path independent of the heat transfer path of heat generated from another component (312) placed within the first shield can (310). For example, heat generated from the first component (311) and heat generated from the second component (312) may be transferred through different paths.

The first component (311) may be spaced apart from the second component (312). The first component (311) and the second component (312) may be components that generate heat during operation of the electronic device (100). The first component (311) may be positioned adjacent to the first shield can (310), and the second component (312) may be spaced apart from the first shield can (310). For example, a distance (d1) between the first component (311) and a side surface (e.g., a side surface (411) of FIG. 4A) may be smaller than a distance (d2) between the second component (311) and the side surface (411). For example, the first component (311) may be positioned within 1 mm from the side surface (411) of the first shield can (310), and the second component (312) may be positioned at least 1 mm away from the side surface (411) of the first shield can (310). The distance (d1) may be 0.15 mm, and the distance (d2) may be at least 1 mm. Unlike the second component (312), the first component (311) may be positioned adjacent to the side surface (411) of the first shield can (310), so that there may be insufficient attachment space between the first heat transfer material (901) and the second heat transfer material (902) positioned on the second component (312). The first heat transfer material (901) may be a TIM applied on the first component (312). The second heat transfer material (902) may be a nano TIM applied to the upper surface (e.g., the upper surface (411') of the first shield can (310) of the first heat transfer material (901). The volume of the first component (311) may be smaller than that of the second component (312). The first component (311) smaller than the second component (312) may have difficulty in surface contact with another heat dissipation structure (903) different from the heat dissipation structure (330) (e.g., the heat dissipation structure (340) of FIG. 3). The other heat dissipation structure (903) may include one of a vapor chamber, a metal plate, or a heat pipe attached to the bracket (904) (or the front metal). The other heat dissipation structure (903) is a wide and flat structure that can dissipate heat through surface contact with the heating element. The first component having a small contact area The heat dissipation path of the component (311) may be difficult to utilize other heat dissipation structures (903). Heat generated from the first component (311) may spread along a different heat transfer path from the second component (312). Heat generated from the first component (311) may spread along a heat transfer path (H1) formed through the heat dissipation structure (330) including a heat conductive material (430) connected to the first component (311) and arranged inside the second shield can (320) to the second shield can (320) or the internal space surrounded by the second shield can (320).

Heat generated from the second component (312) can be released to the outside along a heat transfer path (H2). The heat transfer path (H2) can be formed from a first heat transfer material (901) applied on the second component (312), a second heat transfer material (902) disposed on the first heat transfer material (901), another heat dissipation structure (903) in contact with the second heat transfer material (902), a bracket (904) in contact with the other heat dissipation structure (903), a heat dissipation sheet (905) disposed on the bracket (904), and a display (906) or cover in contact with the heat dissipation sheet (905).

The electronic device (100) can reduce the influence of heat generation between different components (e.g., the first component (311) and the second component (312)) inside one shield can (e.g., the first shield can) by securing a heat dissipation path for each component. The electronic device (100) can diffuse the heat of a high-heat component disposed on a side of the shield can using a heat dissipation structure (330) according to an embodiment. The noise shielding performance of the first shield can (310) and the second shield can (320) can be improved through a tape (450) disposed on the first shield can (310), the second shield can (320), and the heat dissipation structure (330) and including a conductive material.

FIG. 10 is a drawing exemplarily showing the arrangement of shield candles, components and heat dissipation structures in various embodiments.

Referring to FIG. 10, the first shield can (310), the second shield can (320), the plurality of elements (1001), and the heat dissipation structure (1030) may be placed on a printed circuit board (150).

A plurality of elements (1001) may be arranged outside the first shield can (310) and the second shield can (320). The plurality of elements (1001) may be peripheral elements for the operation of elements arranged inside the first shield can (310) and/or elements arranged inside the second shield can (320). For example, the plurality of elements (1001) may include a resistor, a capacitor, an inductor, or a BGA (ball grid array) IC.

Since a plurality of elements (1001) are arranged adjacent to the shield candles (310, 320), it may be difficult to arrange a heat dissipation structure extending along one direction. The heat dissipation structure (1030) may have one end connected to the first shield can (310) and the other end connected to the second shield can (320). The heat dissipation structure (1030) extending from the first shield can (310) to the second shield can (320) may form a bend (1031) to avoid the plurality of elements (1001). Depending on the arrangement of the plurality of elements (1001), the heat dissipation structure (1030) may include a plurality of bends.

In order to avoid elements (1001) arranged on a printed circuit board (1050), the folded portion (1031) of the heat dissipation structure (1030) is arranged parallel to the printed circuit board (1050), so that the utilization of a narrow space on the printed circuit board (150) can be improved.

FIG. 11 is a drawing exemplifying the arrangement of shield candles, elements, and vertically folded heat dissipation structures according to various embodiments.

Referring to FIG. 11, the electronic device (100) may include a first shield can (310), a second shield can (320), a component (311), a plurality of elements (1101), and a heat dissipation structure (1030) on a printed circuit board (150). The plurality of elements (1101) may be arranged between the first shield can (310) and the second shield can (320). The first shield can (310) and the second shield can (320) may have different heights. The heat dissipation structure (1030) may be arranged to connect the first shield can (310) and the second shield can (320) having different heights.

For example, when the height of the components arranged in the internal space of the second shield can (320) is higher than the height of the components arranged in the internal space of the first shield can (310), the second shield can (320) may have a higher height than the first shield can (310). The first shield can (310) may include an opening (1110) for connection with the heat dissipation structure (1030). The second shield can (320) may include an opening (1120) for connection with the heat dissipation structure (1030). The height (h1) from the printed circuit board (150) to the opening (1110) of the first shield can (310) may be lower than the height (h2) from the printed circuit board (150) to the opening (1120) of the second shield can (320). In order to connect the opening (1110) of the first shield can (310) and the opening (1120) of the second shield can (320), the heat dissipation structure (1130) may include a folded portion (1150). The folded portion (1131) of the heat dissipation structure (1130) may be formed to avoid the elements (1101). The heat dissipation structure (1130) folded in a direction perpendicular to the printed circuit board (150) may thermally connect shield cans having different heights. For example, heat emitted from the first component (311) may spread into the interior of the second shield can (320) through a thermally conductive material in the heat dissipation structure (1130).

The heat dissipation structure (1130) may include a first opening (1102) and a second opening (1103) for checking the injection port (1101) and the heat conductive material injected into the heat dissipation structure (1130). The injection port (1101) may be formed at a high position of the heat dissipation structure (1130) to easily supply the heat conductive material to the first shield can (310) and the second shield can (320). For example, the injection port (1101) may be formed at a portion of the heat dissipation structure (1130) connected to the opening (1120) of the second shield can (320) having a relatively high height. The heat conductive material introduced through the injection port (1101) arranged at a high position may easily move into the interior of the first shield can (310).

An electronic device including multiple heat-generating components may include a structure for heat dissipation. Instead of heat pipes or metal plates applied to components adjacent to the shield can, the electronic device may require a structure capable of dissipating heat emitted from components adjacent to the shield can to a relatively lower temperature area.

The electronic device according to the above-described embodiment may include a first shield can, a second shield can, a heat dissipation structure including a heat dissipation material, and a conductive material. The first shield can provide a first space configured to accommodate a component. The second shield can be spaced apart from the first shield can and provide a second space. The heat dissipation structure may have one end connected to the first shield can and the other end connected to the second shield can. A first portion of the heat conductive material may be disposed in at least a portion of an internal space of the heat dissipation structure. A second portion of the heat conductive material may extend from the one end of the heat dissipation structure to at least one surface of the component. A third portion of the heat conductive material may extend from the other end of the heat dissipation structure to the second space. The electronic device may be configured to spread heat generated in the component toward the second shield can through the heat conductive material.

In one embodiment, the heat transfer material may be configured to diffuse heat generated from the component during operation of the electronic device to the second shield can by connecting the component and the space within the second shield can.

In one embodiment, the electronic device may be configured to transfer the heat generated from the component along a path independent of the transfer path of heat generated from other components disposed within the first shield can.

According to the above-described embodiment, the plurality of heat-generating components arranged in the first shield can spread heat through different heat transfer paths, respectively, so that each component can reduce the influence of heat on other components. Due to the reduction in the influence of heat on components within the electronic device, the heat dissipation structure including the thermally conductive material can maintain the performance of the electronic device.

In one embodiment, the component can be spaced apart from the other component. A distance between the component and a side surface of the first shield can in contact with the heat dissipation structure can be shorter than a distance between the other component and the side surface of the first shield can.

By inspecting the heat conductive material, the performance of the heat dissipation structure can be secured.

In one embodiment, the inlet may be closer to the second opening than to the first opening.

Through the supplied heat-conductive material, heat can be spread from the heat-generating component to the cooling region.

In one embodiment, the area of the first outlet may be smaller than the area of the second outlet.

According to the above-described embodiment, the heat dissipation structure can be configured to control the amount of heat conductive material transferred to both ends of the heat dissipation structure according to the area of the first discharge port and the second discharge port. By controlling the amount of heat conductive material required for each location, the manufacturing cost can be reduced.

According to one embodiment, the first exhaust port is formed on a side surface disposed at the one end of the heat dissipation structure, and when one surface of the component in contact with the heat conductive material is viewed in a vertical direction, the component can overlap with the first shield can.

The transferred thermally conductive material may thermally connect the first component and the heat dissipation structure.

In one embodiment, the first outlet can be in contact with the component, and when a face of the component in contact with the thermally conductive material is viewed in a vertical direction, the component can overlap with the first outlet.

According to the above-described embodiment, the heat dissipation structure disposed on one side of the component can be configured to directly supply a heat conductive material to the first component. The component disposed under the heat dissipation structure and in contact with the first discharge port can be in contact with the heat conductive material. The thermal connection between the component and the cooling area (e.g., the second shield can) can be stably maintained.

In one embodiment, the electronic device may further include a tape. The tape may be configured to be attached to a portion of an outer surface of the first shield can, a portion of an outer surface of the heat dissipation structure, and a portion of an outer surface of the second shield can. The tape may secure the heat dissipation structure to the first shield can and the second shield can, and may include a conductive material.

According to the above-described embodiment, the tape can limit vertical movement of the heat dissipation structure by fixing the heat dissipation structure to the first shield can and the second shield can.

In one embodiment, another portion of the thermally conductive material may be applied to an inner surface of the second shield can.

According to the above-described embodiment, based on the thermally conductive material being in contact with the inner surface of the second shield can, heat generated from the component can be spread to the second shield can through the thermally conductive material. The electronic device can be configured to spread heat to a region having a relatively low temperature located around an internal component that is difficult to dissipate heat through a heat dissipation structure having the thermally conductive material.

According to one embodiment, the heat dissipation structure may include a first leg, a second leg, a third leg, and a fourth leg.

In one embodiment, the first leg and the second leg may extend along a side of the first shield can where the opening of the first shield can is formed and may face each other.

By the first leg, the second leg, the third leg, and the fourth leg, the horizontal movement of the heat dissipation structure can be restricted.

According to one embodiment, the heat dissipation structure may include a pipe made of metal material.

In one embodiment, the pipe can be joined to the first leg, the second leg, the third leg, and the fourth leg.

According to the above-described embodiment, the heat dissipation structure and the legs include a metal material and can be welded or joined. The joined legs and the heat dissipation structure can be utilized as a single component.

According to one embodiment, the electronic device may further include a printed circuit board and components.

According to one embodiment, the printed circuit board may have the components, the first shield can and the second shield can arranged thereon. The elements may be mounted on the printed circuit board outside the first shield can and the second shield can. To prevent interference with the elements, the heat dissipation structure may include a folded portion.

According to the above-described embodiments, the electronic device can increase space efficiency through a heat dissipation structure manufactured to avoid interference with components.

In one embodiment, the distance between the opening of the first shield can and the printed circuit board may be different from the distance between the opening of the second shield can and the printed circuit board. The folded portion may have an incline with respect to the printed circuit board.

According to the above-described embodiment, the heat dissipation structure having the folded portion can connect the first shield can and the second shield can having different heights. By being folded vertically to the printed circuit board, elements can be placed between the printed circuit board and the heat dissipation structure, thereby increasing the utilization of the vertical space.

In one embodiment, the thermally conductive material may have viscosity.

According to the above-described embodiment, since the thermally conductive material is a fluid having viscosity, the thermally conductive material can be injected into the interior of the heat dissipation structure. The thermally conductive material injected into the interior of the heat dissipation structure can be transferred to the exterior of the heat dissipation structure, so that the thermally conductive material can be applied to a component or introduced into a shield can. After the thermally conductive material is applied to the component or introduced into the shield can, it can be hardened and take a shape.

In one embodiment, the first shield can may include an opening formed on a side surface of the first shield can and another surface contacting the side surface, in which a portion of the heat dissipation structure is disposed, and the second shield can may include an opening in which another portion of the heat dissipation structure is disposed.

Through the opening formed in the shield can, the heat dissipation structure can be inserted into the inside of the shield can.

In one embodiment, an electronic device may include a heat dissipation structure including a substrate, a component, a shield can, and a heat dissipation material.

According to the above-described embodiment, the plurality of heat-generating components arranged in the first shield can spread heat through different heat transfer paths, respectively, so that each component can reduce the influence of heat on other components. Due to the reduction in the influence of heat on components within the electronic device, the heat dissipation structure including the thermally conductive material can maintain the performance of the electronic device.

According to one embodiment, the electronic device may further include another component. The other component may be disposed within the shield can and may dissipate heat while the electronic device is operating. The heat transfer path of the other component may be independent of the heat transfer path of the component.

Referring to FIG. 12, in a network environment (1200), an electronic device (1201) may communicate with an electronic device (1202) via a first network (1298) (e.g., a short-range wireless communication network), or may communicate with at least one of an electronic device (1204) or a server (1208) via a second network (1299) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1201) may communicate with the electronic device (1204) via the server (1208).

In some embodiments, the electronic device (1201) may omit at least one of these components (e.g., the connection terminal (1278)), or may have one or more other components added. In some embodiments, some of these components (e.g., the sensor module (1276), the camera module (1280), or the antenna module (1297)) may be integrated into a single component (e.g., the display module (1260)).

The processor (1220) may include various processing circuits and/or multiple processors. For example, a “processor” as included and used in the claims may include multiple processing circuits or may include at least one processor, and one or more of the at least one processors may be configured to perform the multiple functions recited independently and/or collectively in a distributed manner. The terms “processor,” “at least one processor,” and “one or more processors,” as used herein, indicate that a plurality of functions are performed, and may include one processor performing some of the recited functions and other processor(s) performing other of the recited functions, or a single processor may perform all of the recited functions. Additionally, the at least one processor may include a combination of processors that perform the various functions enumerated or disclosed in a distributed manner. The at least one processor may execute program instructions to achieve or perform the various functions. The processor (1220) may control at least one other component (e.g., a hardware or software component) of the electronic device (1201) connected to the processor (1220) by executing, for example, software (e.g., a program (1240)), and may perform various data processing or calculations. According to one embodiment, as at least a part of the data processing or calculations, the processor (1220) may store a command or data received from another component (e.g., a sensor module (1276) or a communication module (1290)) in a volatile memory (1232), process the command or data stored in the volatile memory (1232), and store result data in a nonvolatile memory (1234). According to one embodiment, the processor (1220) may include a main processor (1221) (e.g., a central processing unit or an application processor) or an auxiliary processor (1223) (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together with the main processor (1221). For example, when the electronic device (1201) includes the main processor (1221) and the auxiliary processor (1223), the auxiliary processor (1223) may be configured to use less power than the main processor (1221) or to be specialized for a given function. The auxiliary processor (1223) may be implemented separately from the main processor (1221) or as a part thereof.

The auxiliary processor (1223) may control at least a portion of functions or states associated with at least one of the components of the electronic device (1201) (e.g., the display module (1260), the sensor module (1276), or the communication module (1290)), for example, on behalf of the main processor (1221) while the main processor (1221) is in an inactive (e.g., sleep) state, or together with the main processor (1221) while the main processor (1221) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1223) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1280) or a communication module (1290)). In one embodiment, the auxiliary processor (1223) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. Such learning may be performed, for example, in the electronic device (1201) itself on which the artificial intelligence model is executed, or may be performed through a separate server (e.g., server (1208)).
